::. I have only sponsored one member but under their name it says "Referral Passed Up to Your Sponsor." Aren't the 2nd and 4th members passed up to my sponsor, instead of the 1st member?

That's correct.  The 2nd and 4th "paid members" are passed up to your sponsor.  Free members do not pass up.  The phrase "Referral Passed Up to Your Sponsor" is a heading.  The list of members sponsored by you and passed up to your sponsor will appear BELOW this heading.
